| Abstract [eng] |
There has been lot of research and experiment available for the orthogonal turning operation on different materials varying the input parameters. For the material S355 there is no experiment available regarding the analysis of vibration test, surface roughness and chip inspection calculations. This research project shows the experiment test results of two workpieces undergoing longitudinal orthogonal turning operations with varying cutting speed. Before the experiment, the bump test was conducted on the workpiece and the cutting tool to determine the resonance frequency. Total 10 experiments performed with each workpiece. The vibration test is carried out during each experiment and then the frequency is measured using accelerometer. After the completion of the experiments the chip is collected for further investigation. In this research paper, surface roughness is calculated using the surface roughness tester. The chip thickness is measured from the collected chips using Vernier scale and the other output parameters like coefficient of plastic deformation, shear angle and resultant force is calculated using the equations. The effect of this output parameters with varying cutting speed is shown and plotted in graph. The result shows the machinability conditions and quality of material S355 undergoing orthogonal test varying different cutting speed. The result of this experiment would be beneficial for the company using the same workpiece and operations. The further research can be done using the different material and the comparison table or chart can be made to analyse the whole process of chip formation and determine the best condition to achieve the most efficient and high quality machining result. |
